2. Setup and Assembly
Before starting assembly, ensure you have a clean, well-lit workspace. While no special tools are strictly required, a pair of plastic model nippers and a hobby knife can greatly improve the building experience and final appearance.
2.1. Unpacking and Part Identification
- Carefully open the packaging and remove all runners (plastic frames with parts).
- Familiarize yourself with the included instruction booklet, which details part layouts and assembly steps.
- Verify all runners and parts are present and undamaged.

Figure 2.1: Overview of included parts and accessories.
2.2. General Assembly Guidelines
- Cut parts from the runners using nippers, leaving a small nub. Trim the nub flush with a hobby knife for a clean finish.
- Follow the numerical order in the instruction booklet for optimal assembly flow.
- Pay close attention to part orientation and connection points to avoid damage.
- The estimated assembly time is approximately 30 minutes, though individual times may vary.
2.3. Key Assembly Features
- SEED Action System: This model incorporates the SEED Action System, allowing for dynamic posing. Assemble joints carefully to ensure full range of motion.
- Real Metallic Gloss Injection: Gold parts utilize a special injection molding process for a realistic metallic sheen. Handle these parts with care to preserve their finish.
- Proud Defender: The backpack unit, known as the Proud Defender, can be attached to the main body or displayed separately. Its white wings feature 8 sliding points for expanded deployment.
- Weapons and Accessories: Assemble the various weapons including the Beam Rifle, Beam Sabers, Beam Shield, and the 'Futsunomitama' katana. The katana blade features two different surface finishes for enhanced texture.

3. Operating and Posing
Once assembled, your Mighty Strike Freedom Gundam can be posed in various dynamic stances thanks to its advanced articulation.
3.1. Articulation Points
- Head and Neck: The head and neck joints allow for a wide range of movement, enabling expressive poses.
- Shoulders and Arms: The SEED Action System provides extensive articulation in the shoulders and arms for weapon handling and action poses.
- Torso: The torso features flexibility for forward, backward, and side-to-side bending.
- Hip Joints: The hip joints are designed to swing individually up and down, allowing for poses where the toes are extended and aligned.
- Wrist: The wrist features an additional movable axis for broader expression when holding weapons.
3.2. Weapon and Accessory Handling
- Beam Rifle: The two beam rifles can be connected to form a single, more powerful weapon.
- Waist Railguns: The waist-mounted railguns are deployable, allowing for the reproduction of a full-burst attack state.
- Beam Sabers: The beam sabers can be connected to form a twin-bladed weapon using the included grip.
- Head Cannons: The head-mounted cannons can be reproduced in their deployed state by replacing parts.

4. Maintenance
Proper maintenance will ensure the longevity and appearance of your model kit.
4.1. Cleaning
- Regularly dust your model using a soft brush or compressed air.
- For fingerprints or smudges, gently wipe with a soft, lint-free cloth. Avoid harsh chemicals or abrasive materials.
- Be especially careful when cleaning parts with the Real Metallic Gloss Injection finish to prevent scratching.
4.2. Storage
- Store the model in a cool, dry place away from direct sunlight to prevent plastic degradation and color fading.
- If storing for extended periods, consider a display case to protect against dust and accidental damage.
4.3. Handling
- Handle the model by its larger, more robust sections. Avoid gripping small or delicate parts.
- When posing, apply gentle, even pressure to joints. Do not force movement beyond its natural range.
5. Troubleshooting
Here are solutions to common issues you might encounter:
- Loose Joints: If a joint feels too loose, you can apply a thin layer of clear nail polish or a specialized hobby joint-tightening solution to the peg and let it dry before reassembling.
- Parts Not Fitting: Ensure you are using the correct parts for each step. If a part is too tight, carefully trim any excess plastic (nubs) with a hobby knife. Do not force parts together, as this can cause breakage.
- Broken Parts: For minor breaks, plastic cement designed for model kits can be used. For significant damage, replacement parts may be available from the manufacturer or hobby retailers.
- Stickers/Decals Not Adhering: Ensure the surface is clean and dry. Use tweezers for precise placement and a cotton swab to gently press down and remove air bubbles.
